The present invention relates to the electrical, electronic, and computer arts, and more specifically, to generating a reminder for an item.
It is well known that the memory of individuals is not perfect. People tend to forget items or objects, or forget performing certain tasks, when they prepare to leave their house, office, hotel or, generally, any location. Examples of such items include a computer charger, a power converter, a wallet, a suit, an identification card, a phone charger, a notebook, a picture, or other objects that may be important or relevant for a given context. Tasks may include pre-boarding an airline flight, making a hotel reservation, and the like. Depending on the user profile or context (such as a busy person, an inattentive person, a location, an event type, and the like), the degree of forgetting such items and tasks may vary. For instance, some users may remember to pack a “suit,” but may forget to pack a suitable “belt”; some users may forget their wallet. Some users may not select items that are relevant or essential for the defined context, such as the context associated with a destination or location, the context of an event, and the like. In the real world, there are many types or categories of items and tasks that may be forgotten depending on the user context, event context, user profile, and the like. It can be a challenge to inform a system about items that may be forgotten.
In one example scenario, a vast filtering system is utilized at one train station in London (the Baker Street train station) to collect the items left behind as people flow through the city's transit system each day. The cost to the city is sixty-five staff employees sorting through hundreds of thousands of lost and forgotten items at the depot, which costs consumers' tens of millions of dollars. According to the transparency data, the Baker Street Lost and Found team sorted through 332,077 items during the first three months of 2018. According to the team, an accurate price for what it costs to return each item is £100, illustrating the cost of loss. The data reveals that very few items are claimed. Overall, 20% of the stock is claimed within three months; after that time, the stock passes into the city's possession.
Individuals often remember their forgotten items when seeing other relevant or related objects (such as, when a user pulls out his computer, the user may remember a power charger or power convertor; when a user pulls out a suit, the user may remember the appropriate pair of shoes, and the like). Such recollection, however, can come too late to mitigate the situation, either while traveling to the destination or after arrival.
Embodiments of the present disclosure provide a platform for reminding users about items for a given event, such as a travel or trip event. In one example embodiment, the platform is a conversational platform and the item is a physical item, a task to be performed, and the like. The reminders are based on an understanding of a plurality of contexts and attributes pertaining to “forgetting an item or task,” known as item reminder enhancement factors herein. In one example embodiment, conversational content is generated, and a user or group of users is contextually probed with the conversational content to obtain information associated with an event.
In one example embodiment, a method and system for assisting a user or group of users in planning, preparing for, and participating in an upcoming event is disclosed. The event may be a travel event, a trip, a conference, a work event, and the like. In an example embodiment, an upcoming event of a user or groups of users is received; a set of items related to the event for which the user or groups of users are to be reminded is determined; item reminder enhancement factors are determined in response to the upcoming event and the determined list of items; conversational content is generated based on features, characteristics and affinity measures of the items and by applying content selection models to a plurality of potential content; a conversational trigger signal is determined; and the user or groups of users are contextually probed with the conversational content. The probing is conducted via one or more text/voice-based devices, a conversational system, and the like. The conversational content is, for example, questions, dialog, text or voice-based checklists, and the like. The conversational trigger signal is, for example, an interaction of a user with a device, sensing the user based on a proximity sensor, detecting an expiration of a time trigger, receiving text generated using voice recognition, and the like. In an example embodiment, items that are missed by the user are dynamically routed to, for example, the user. The routing of the items is based, for example, on the degree of importance of the item.
As used herein, “facilitating” an action includes performing the action, making the action easier, helping to carry the action out, or causing the action to be performed. Thus, by way of example and not limitation, instructions executing on one processor might facilitate an action carried out by instructions executing on a remote processor, by sending appropriate data or commands to cause or aid the action to be performed. For the avoidance of doubt, where an actor facilitates an action by other than performing the action, the action is nevertheless performed by some entity or combination of entities.
One or more embodiments of the invention or elements thereof can be implemented in the form of a computer program product including a computer readable storage medium with computer usable program code for performing the method steps indicated. Furthermore, one or more embodiments of the invention or elements thereof can be implemented in the form of a system (or apparatus) including a memory, and at least one processor that is coupled to the memory and operative to perform exemplary method steps. Yet further, in another aspect, one or more embodiments of the invention or elements thereof can be implemented in the form of means for carrying out one or more of the method steps described herein; the means can include (i) hardware module(s), (ii) software module(s) stored in a computer readable storage medium (or multiple such media) and implemented on a hardware processor, or (iii) a combination of (i) and (ii); any of (i)-(iii) implement the specific techniques set forth herein.
Techniques of the present invention can provide substantial beneficial technical effects. For example, one or more embodiments provide one or more of:
These and other features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.
In one example embodiment, an intelligent system, such as a conversational platform, is configured on a computing device (such as a cellular phone and the like), a voice-enabled device (such as Alexa®, Google Home™, and the like—hereinafter a conversational device), a sensor, a device available in a smart home, a vehicle, and the like to automatically engage a user with conversational content. In situations where items have been forgotten, the intelligent system creates amelioration actions that can dynamically identify forgotten items, replacement items, or both; and trigger the delivery of the forgotten items, replacement items, or both. For example, a neighbor of the user who is available to deliver or transport the item may be identified, a replacement item and pick-up location may be identified, transportation and delivery options by a courier may be arranged (for picking up and delivering the item), and the like.
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as Follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as Follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as Follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

As used herein, an event is related to a personal event (such as a vacation, a wedding, a birthday, an exercise, an entertainment event, and the like), a business event (such as a meeting, a conference, and visiting an office, a bank, or a driving license office), and the like. Non-exhaustive examples of context related to an event include a location, a time/duration of the event, a predicted task associated with the event, an event type (such as a vacation, a wedding, a birthday, an exercise, an entertainment event, a workshop, a meeting, an office visit, and the like), a service (such as banking, an embassy visit, a motor vehicle service, and an immigration service), and the like. Similarly, non-exhaustive examples of items or objects for a travel or trip event that may be forgotten include a computer charger, a phone, a phone charger, a subscriber identity module (SIM card), a power bank, a power converter, a wallet, a suit, an identification card, a document or certificate, a notebook, a photo or picture, and the like.
The system identifies Abdi's voice when he speaks to a conversational device requesting to play a song the night before his trip; selects two content items {<Do you have your yellow fever card?>, <Do you have your Green Card?>} based on their “critical” levels and sends these items to the conversational device to play for Abdi; and receives “Yes” for <Do you have your Green Card?> and updates the checklist accordingly. In the morning, when Abdi is about to leave for the airport, the conversational device repeats the questioning for the remaining items. In this example, Abdi ignores the questioning (as detected by sensors in the home). The system therefore sends the conversational content to Abdi's cellular phone or car. When Abdi starts the engine of his car, it triggers the voice-controller of the car to obtain conversational content from the cloud. In this case, the system also warns Abdi by stating the possible implications of not taking various items. The implications are determined, for example, based on an analysis of details regarding the item (such as an importance of the item in relation to the user's travel details, including, for example, details such as destination profile, event profile, and the like) and an analysis of historical implications (such as historical implication data collected over a period of time, including, for example, a list of implications resulting from items being forgotten in the past).
Event Identification
In one example embodiment, the event identifier 408 identifies an event, such as travel or a trip event, for a user or group of users by employing one or more machine learning algorithms. The machine learning algorithms use a plurality of data points such as calendar information (such as an Outlook calendar, a Google calendar, and the like), messages, emails, conversations, and the like to identify upcoming events (such as a workshop, travel to the U.S., and the like). The computing system 400 may also explicitly receive an identification of an upcoming event from the user directly, such as via a graphical user interface (GUI) or speech recognition system.
A customized machine learning model 436, such as a named entity recognition (NER) algorithm, can be employed to extract and classify named entities in text data into pre-defined event categories, such as a name of an organization, a location, and the like. The NER algorithm further uses linguistic grammar-based techniques as well as statistical machine learning models. In one example embodiment, the event identifier 408 uses the event context builder model 432 to learn various contextual information related to the event and semantically characterize the event. If necessary, the event identifier 408 detects and, if necessary, verifies with the user expected travel information obtained from a conversation. The expected travel information is obtained by employing speech recognition, using a conversational device, and the like.
Generating and Associating Items with Events
The item generator 412 generates a list items associated with an identified event. In one example embodiment, the list includes the identity of a set of items that a user or a group of users needs to bring for an event, a set of tasks to perform for an event, or both. The items are, for example, a toothbrush, a shaver, a special permit or visa, and the like. The list of items is generated based on a trip the user is taking or participating in, a work event, and the like. In one example embodiment, item to item association is learned (such as the user typically takes toothpaste when the user takes a toothbrush, a comb, and a razor on overnight trips) using historical observations from past events.
In one example embodiment, the computing system 400 is trained to determine and generate (via the item generator 412) a list of items <I> through the analysis of an upcoming event E, an identified context C, and a user profile P. The user profile includes, for example, an indication of the person's current state (such as a busy person, an inattentive person, and the like), a person's history (such as a history of forgetting certain items), a list of historical implications due to items being forgotten, and the like. In one example embodiment, the method of generating items further categorizes each item by type and context (such as important, less important, and the like). Various affinity measures between event-item <E, I> and Item-Item <I, I> are determined. For example, association rule learning or decision-tree methods can be used to create the various affinity measures. Alternatively, identified items needed for the predicted or detected event may include items received from a system generated list of items using predictive models, items received from the user (i.e., a user-supplied list of items), items that may be detected from a conversation (such as items identified during an analysis of data from a smart speaker device) or from text messaging, and the like.
In one example embodiment, the item generator 412 generates a list of items based on the characteristics of a travel event, past user history, and the like. The computing system 400 further learns of one or more items (such as items that the user carried during previous travels or trips) and contexts (such as historical contexts of trips, historical characteristics of destinations, events, locations, prior consequences of items being forgotten, and the like) based on historical data. An implication or consequence of an item being forgotten is determined and may be related to time, money, harassment, lost productivity, and the like. As described above, the implication is determined, for example, based on an analysis of a combination of details regarding the items (such as item importance in relation to the user's travel details (including, for example, a destination profile, event profile, and the like) and an analysis of historical implications (such as, for example, historical implication data collected over a period of time)). Moreover, a consequence level is determined based on the computed risk score, as described more fully below. The consequence is also based on contextual information, such as time, money, and the like associated with the user event (available in the first set of user data). If necessary, a percentage value can be computed using association rules for each portion of context information and the percentage value can be attached to the determined implication/consequence (such as a percentage value indicating 50% time implication, 75% lost productivity, and the like).
Note that the user profile P can be constructed from a plurality of user data such as that obtained from the user's calendar, emails, Amazon Echo or Google Home device, smartphones, smart watches, sensors and cameras in the home and car, and the like to build up a profile of the items historically carried by a user, preferences for time and modality for a reminder (such as early in the morning via audio) and which modalities the user responds best to, and the like. The user profile can be enhanced with additional data relating to events and items taken on a trip, and the user's responses to reminders. For example, if a user responds that they would like a reminder to bring a belt on a trip, that need may be retained for a future trip. The user data can further contain historical user travel information, historical user calendar information, historical user behavioral data, a previous history of implications or risks due to forgotten items, a user profile, historical user interactions with devices, and the like.
In one example embodiment, estimates of the probability that certain items will be forgotten can be gleaned from observations of other users and their proclivity to forget the items, potentially weighted based on a degree of similarity of the other users to the given user. An estimate of the cost of forgetting a given item can be deduced by considering the average cost of trips taken when the item is lost versus when the item is not lost.
In one example embodiment, the probability of forgetting an item is estimated by using population averages for the item being forgotten and the given user's propensity to forget items in general compared to the population at large. For example, the probability of a typical person in the population forgetting to bring a toothbrush on a typical trip involving an overnight stay might be 5%, but the given individual in question may be observed to be twice as forgetful as a member of the general public. As a result, the system will estimate the user's likelihood to forget a toothbrush as 2×5%=10%.
The item generator 448 maps the requisite items needed for an event using event categorization (for categories such as a meeting, a conference, a class, and the like). For example, a typical trip to the U.S. might have the following requirements:
In one example embodiment, each item may be represented on a knowledge graph where the event is associated with a set of requirements, as described more fully below in conjunction with
In the example method 600 of
Generating Conversational Content
The computing system 400 also generates contextualized conversational content. In one example embodiment, the contextualized conversational content corresponds to items on the list of items identified for the event by employing custom trained machine learning models and the like. The conversational content is, for example, a list of questions (such as one or more questions for each item), a text-enabled or voice-enabled checklist, a dialog, and the like. The method of generating contextualized conversational content further includes, for example, evaluating one or more effective strategies to best engage with users for some selected items. In one example scenario, a semantics-based technique is employed to tag generated conversational content with a priority level, an importance level, a time aspect, a sensitivity, an appropriateness in connection with when to trigger the conversation (such as some questions in front of a child for some items may not be appropriate), and the like. This can be done in two steps. First, each of the generated conversational content items is analyzed (such as using NLP or any relevant content analytics algorithm) to understand the type and nature of the content item. Second, based on the characteristics of the travel or event to which the content items are generated, properties of the content item such as a priority level (such as 3<High>, 2<Medium>, 1<Low>, and 0<Negligible>), an importance level (computed based on the priority level), a time (suggesting when to trigger the conversational content to the user), and the like are inferred. As an example, consider generating a few simple conversational elements from travel event E (such as a calendar entry of “Travel to Dubai for a client meeting on April 30”) and a list of items I (such as {Suit, Charger}) for the user Abdi. The conversational elements may include:
In the method below, a priority tagging mode, an NER model, a response strategy, and a dialogue model are used to identify the correct response strategy and correct response to return to the user:
4 response_strategy_list←apply response_strategy_model to dialogue_model, user_profile
5 if response_strategy_list>0
6 preferred_response_strategy←find highest confidence_score
7 else preferred_response_strategy←request_user_to_repeat_sentence
8 response_to_user←apply user_profile, preferred_response_strategy to dialogue_model
9 return response_to_user
In one example embodiment, the above pseudocode algorithm outputs (see line 9) the response to the user (response_to_user) given the various machine learning models (user profile, priority_tag_model, named_entity_recog_model, response_strategy_model, dialogue model, and the like) and other input parameters (user_response, user_profile, time, list_reminder, and the like) as input (see line 1). The model named_entity_recog_model is applied to the received user response (user_response) to determine dialogue entities key_dialogue_entities (see line 2), which will be used to determine the key_priority_topic. The priority_tag_model model is applied to the tuple <key_dialogue_entities, list_reminder, time> to determine the key_priority_topic (see line 3).
The pseudocode algorithm determines the list of response strategies response_strategy_list by applying the response_strategy_model mode to the pair <dialogue_model, user_profile> (see line 4). A check is then performed to determine if the determined list of response strategies contains at least one response strategy (see line 5). If the list of response strategies contains at least one response strategy, the pseudocode algorithm finds the highest confidence_score, which will be selected as preferred_response_strategy (see line 6).
If the list of response strategies contains no response strategy, the pseudocode algorithm triggers the contextual item reminder assistant system to engage with the user (the preferred_response_strategy←request_user_to_repeat_sentence; see line 7). The pseudocode algorithm determines the response to the user by applying both the user profile and preferred response strategy to the dialogue model (see line 8). The final value of the response is then returned to the user (see line 9).
In one example embodiment, the computing system 400 further detects an item from a conversation (using, for example, speech/voice recognition methods and natural language processing) and triggers the conversational content generator 416 to generate the conversation. For example, the conversational content generator 416 may output conversation contents such as:
In one example embodiment, the generation of conversational content further employs a variant of question generation approaches such as template-based (that helps to produce what/why/how types of questions for conversation), syntax-based or semantics-based, and the like.
Contextual Conversation Trigger Detection
In one embodiment, the computing system 400 employs a rule-based algorithm, a learning-based algorithm, or both to determine one or more triggers that will be used to auto-trigger a conversation with a user pertaining to item reminders. In one example embodiment, the method of determining one or more triggers further comprises sensing the user based on proximity sensors (such as sensors available on the user's mobile phone), based on proximity to a geo-fencing region, and the like; learning a trigger indicator based on the attributes of items such as sensitivity, characteristics, context (such as a location, a time of the day, a crowd-density, and the like); and detecting the voice/sound of the user while the user is speaking to a voice-controlled device (such as the user requesting a virtual assistant to play a song), or using user-specified trigger events (such as an electronic to-do list) or real-time instrumentation of user interaction. The method of determining one or more conversational triggers may further include determining the context regarding when to auto-trigger the conversation based on conversation sensitivity and appropriateness. For example, a user's voice may be identified when the user speaks to a virtual assistant requesting to play a song the night before a trip.
Auto-Triggering Conversation
Re-Routing of Items
In one example embodiment, as described above, the system creates amelioration actions that can dynamically trigger the routing of forgotten or replacement items, such as identifying a neighbor of the user to deliver or transport an item, identify a replacement item, arrange transportation and delivery options by a courier (such as picking up and delivering the item), and the like. In one example embodiment, for items that have been forgotten, mediation to find a route to either deliver the item to the user or find a replacement item is computed. In the former case, individuals in the user's network who are in the vicinity of where the forgotten item was left, for example, can be contacted. If available, they can pick up the item while en route to where the user is currently located. The individuals are identified based on the user's contacts list (such as phone directory, email, Facebook account, and the like) and are ranked, for example, based on the distance from the user's home location upon arrival, based on the social connection with the user (such as individuals with few interactions with the user would be ranked lower than other users), and the like. Notifications are then sent to the individual asking whether they would be able to drop off the forgotten item. In another scenario, data on a courier service (such as DHL, Uber, Flight, and the like) is aggregated and evaluated to determine their availability and cost for delivering the item. The information is then presented to the user.
In one example embodiment, data from stores, such as online stores and physical stores, are mined to find the availability of a forgotten item and options are presented to the user describing where they can order the item for delivery to their location, where they can pick up the item, and the like. This may be presented on a computing device, via a conversational system, and the like.
In one example embodiment, the system provides warnings to the user via a GUI, wherein the warnings are in the form, for example, of changing the color of a portion of a GUI, vibrating a computing device, and the like based on a detected concern level (such as the user is still at home at 2 pm when a flight is at 3 pm) or based on certain items not being checked off an item list. In the instance where the risk-level is above a certain threshold, the system triggers the amelioration actions described above. The GUI can be configured to alert, trigger, and notify the relevant user of the appropriate actions to take or to provide feedback to the user on the user's computing device. For example, a notification of “DO NOT FORGET SUIT” or “RESCHEDULE FLIGHT” may be displayed to the user on a GUI.
The multidimensional array is an array that has more than two dimensions. A two-dimensional array uses two subscripts for indexing, namely, a row index and a column index. A multidimensional array uses additional subscripts for indexing. For example, a three-dimensional array uses three subscripts, namely, a rank array dimension 1 (such as the row), dimension 2 (such as the column); and dimension 3 (such as a page). As dimensions are added, corresponding subscripts are added. For example, a four-dimensional array has four subscripts: the first two reference a row-column pair; and the second two access third and fourth dimensions of data. A dimension of the multidimensional risk array can include, for example, information related to items, travels, events, job, health, relationship, cost, and the like. Another dimension can be a risk of a combination of two or more items or health issues. Another dimension can be an indication of whether entry at a point of entry to a destination target (such as a country, an event entrance, and the like) is denied.
Given the discussion thus far, it will be appreciated that, in general terms, historical data is used to understand, for a given user, what items are typically useful but often forgotten for a given event. Suitable ameliorating processes are automatically triggered once an item is recognized to be lost. Novel employment of machine learning (ML) algorithms or techniques (such as, predictive models) to (a) estimate the cost of forgetting an item, (b) estimate the probability that certain items will be forgotten, and (c) compute the risk associated with losing such items is disclosed. Machine learning models are used to generate contextualized conversational content as an effective and natural way of engaging with users by issuing reminders of items that might be forgotten for a given event and to determine at least one conversational trigger for issuing contextualized conversations, issuing reminders to a user, and controlling user devices based on contextual information (such as priority level, location, a time/duration of the event, a predicted task associated with the event, an event type, a service, and the like) related to the conversational content, an analysis of a user's feedback, or both.
Given the discussion thus far, it will be appreciated that, in general terms, an exemplary method, according to an aspect of the invention, includes the step of identifying the upcoming event based on user data (440, 604-608); obtaining context for determining a list of items useful for the upcoming event (604-608); determining, using the context, the list of items for the identified upcoming event (616); determining item reminder enhancement factors in response to the upcoming event and the determined list of items (612); determining content selection models based on the context, the user data, and the item reminder enhancement factors (804); generating conversational content for engaging the user or group of users by applying the content selection models to a plurality of potential content (808); determining a conversation trigger signal (420, 440, 812); and presenting the conversational content to the user via a computing device in response to receiving the conversation trigger signal (420, 816).
In one example embodiment, the determining the list of items further comprises receiving an identity of one or more items from a plurality of sources based on one or more of a signal sent from an item, a list of items generated by a system (412) by using predictive models, a user-supplied list of items, and one or more items detected during conversation (816). In one example embodiment, a likelihood that the user or the group of users will forget an item on the list of items is learned; an aspect of context-sensitive implications or risks associated with the item on the list of items when forgotten is determined; and a degree of item importance based on the context-sensitive implications or risks is determined.
In one example embodiment, the determining the conversation trigger signal is performed based on one or more of detecting a user interaction with a specified computing device, sensing the user based on a proximity sensor, sensing the user based on proximity to a geo-fence region, detecting an expiration of a time trigger, receiving text based on voice recognition, and analyzing attributes of an item on the list of items (812). In one example embodiment, the determining the conversation trigger signal further comprises: learning a trigger indicator based on one or more attributes of an item on the list of items; and detecting the trigger indicator based on one or more of a user speaking to a voice-controlled device, a user-specified trigger event, and a real-time instrumentation of user interaction (420, 812).
In one example embodiment, the determining the conversation trigger signal further comprises determining context regarding when to auto-trigger a conversation based on conversation sensitivity and appropriateness (420, 812). In one example embodiment, at least one model to rank the potential content according to attributes of an item on the list of items and the user data is established and one or more forgotten items are dynamically routed based on an analysis of the degree of item importance (904-916). In one example embodiment, a cost of forgetting at least one item on the list of items is estimated. In one example embodiment, the identifying the upcoming event further comprises employing a machine learning algorithm (436) using a plurality of data points, the plurality of data points comprising one or more of calendar information, a message, an email, and a conversation (500).
In one example embodiment, the user data comprises: a user profile (440), the user profile comprising data obtained from a user's calendar, an email, and a user device; and one or more of a profile of items historically carried by a user, a preference for time and modality of reminder, a user's response to a reminder, historical user travel information, historical user calendar information, historical user behavioral data, a previous history of implications or risks due to forgotten items, and historical user interactions with a user device. In one example embodiment, the identifying the upcoming event further comprises obtaining a first set of user data (604); and predicting at least one item selection factor based on the identified upcoming event and the first set of user data, wherein the identification of the upcoming event is based on associated contextual information in the first set of user data (612). In one example embodiment, the at least one item selection factor is a degree of forgetting an item, an importance level, a priority level, a sensitivity, a first context, and an affinity measure (612).
In one example embodiment, the list of items is determined based on the predicted item selection factors and the first set of user data (616). In one example embodiment, the first set of user data comprises one or more of historical user travel information, user calendar history, historical user behavioral data, a previous history of implications or risks due to a forgotten item, a user profile, and historical interactions with a user device (604). In one example embodiment, the generating the conversational content further comprises: obtaining an item set <I> and user data <U>; and generating a set of conversational content generation models based on the item set <I>, the user data <U>, and an analysis of other contextual data, wherein the conversational content is generated by applying the set of conversational content generation models (804). In one example embodiment, an amelioration action is determined, the amelioration action being one or more of dynamically triggering the routing of a forgotten item (916), identifying a replacement item (912), identifying an individual to transport the forgotten item (912), and arranging transportation and delivery options by a courier for the forgotten item (912).
In one example embodiment, a computer implements a machine learning system, said computer comprising: a memory; and at least one processor, coupled to said memory, and operative to perform operations comprising: identifying the upcoming event based on user data (440, 604-608); obtaining context for determining a list of items useful for the upcoming event (604-608); determining, using the context, the list of items for the identified upcoming event (616); determining item reminder enhancement factors in response to the upcoming event and the determined list of items (612); determining content selection models based on the context, the user data, and the item reminder enhancement factors (804); generating conversational content for engaging the user or group of users by applying the content selection models to a plurality of potential content (808); determining a conversation trigger signal (420, 440, 812); and presenting the conversational content to the user via a computing device in response to receiving the conversation trigger signal (420, 816).
In one example embodiment, a non-transitory computer readable medium comprises computer executable instructions which when executed by a computer cause the computer to perform the method of: identifying the upcoming event based on user data (440, 604-608); obtaining context for determining a list of items useful for the upcoming event (604-608); determining, using the context, the list of items for the identified upcoming event (616); determining item reminder enhancement factors in response to the upcoming event and the determined list of items (612); determining content selection models based on the context, the user data, and the item reminder enhancement factors (804); generating conversational content for engaging the user or group of users by applying the content selection models to a plurality of potential content (808); determining a conversation trigger signal (420, 440, 812); and presenting the conversational content to the user via a computing device in response to receiving the conversation trigger signal (420, 816).
